For things like pppd, there is always a debug option you can turn on.
Not sure how wvdial or kppp do things, but if they use pppd under the
covers, try turning on any debug options. Then set up syslog to log
things at the debug level to (for example) /var/log/debug. That will
dump quite a lot of stuff, including any control messages thatgo
backwards and forwards.
If you can get that far, you should be able to see what kind of messages
are going through before things sieze up. I am not sure where you can go
exactly from there, but if might give you/us some clues.
